Latin American Energy EPC Migrates 380 Electrical Engineering Seats to GstarCAD (Illustrative Scenario)
A multinational Latin American electrical transmission EPC contractor executing 500kV substations and smart grid interconnections transitioned 380 electrical schematic and structural drafting seats to GstarCAD 2027. Complying with IEC 61850 and IEC 60617 standards, the company achieved total software license independence and eliminated annual subscription spikes, saving $2.28M over 5 years.
Illustrative scenario. This case study is a composite example built from typical enterprise CAD migration patterns. The organization, the people described and all figures are illustrative and do not describe a specific GstarCAD customer.

Executive Audit Summary
Scale: 380 Floating Network Seats | 5-Year Net TCO Preserved: $2,280,000 Saved over 5 Years (82% TCO Reduction) | Binary DWG Accuracy: 100.00% Zero-Loss | Retraining Downtime: 0 Business Hours
1. Industrial Challenge & Recurring License Rental Bottleneck
Constructing high-voltage AC and DC transmission substations across the Andes and Brazilian coastal corridors, the engineering firm employs over 750 electrical designers, protection and control (P&C) specialists, and civil foundation engineers. Typical project packages involve thousands of single-line diagrams (SLD), three-line AC/DC schematics, relay panel wiring tables, and substation physical layout drawings.
The firm previously used AutoCAD and AutoCAD Electrical. However, mandatory transition to individual Named User licenses severely crippled their collaborative multidisciplinary delivery model. Substation drafting requires flexible team scaling between project milestones, and sharing floating licenses across regional offices in Santiago, Lima, and São Paulo was vital. Recurring Autodesk software rental costs exceeded $750,000 per year, prompting executive leadership to mandate an immediate transition to perpetual floating network licenses.
2. 30-Day Technical Verification & Standard Compliance Protocol
The technical steering committee executed a thorough 30-day trial on the 500kV Atacama Solar Interconnection project:
- IEC 60617 & IEEE Graphical Symbol Consistency: Electrical engineers verified that thousands of proprietary dynamic electrical blocks—including transformer winding symbols, circuit breakers, and protection relay contacts—retained all connection attributes and visibility states without corruption.
- Automated Terminal Strip & Cable Schedule LISP Porting: The firm’s 84 in-house AutoLISP routines that automate cross-reference terminal block numbering, wire tagging, and cable pulling schedules operated in GstarCAD 2027 with 100% execution fidelity.
- Lightning Protection & Grounding Grid DWG Calculation: Heavy grounding grid layout drawings containing dense conductor meshes and IEEE 80 soil resistivity calculation overlays loaded and zoomed instantly without viewport lag.
- Secondary Relay Panel C# .NET Plugin Migration: A custom C# .NET terminal jumper checking tool was recompiled for GstarCAD in less than half a day by updating assembly references to
GsMgd.dllandGsDbMgd.dll.
3. Five-Year Total Cost of Ownership (TCO) Financial Audit
A rigorous five-year financial ledger comparison between Autodesk Named User subscription recurring rental and GstarCAD perpetual floating network licensing reveals massive capital savings:
| Investment Horizon | Autodesk® Subscription Model | GstarCAD® Perpetual Network | Net Capital Preserved |
|---|---|---|---|
| Year 1 (Initial Perpetual Licensing & Server Setup) | $752,400 (380 Named User Subscriptions) | $285,000 (Perpetual Floating Network Pool) | $467,400 (62% Savings) |
| Year 2 (Annual Maintenance vs Recurring Rent) | $790,020 (+5% Inflation) | $42,750 (Optional Maintenance Upgrade) | $747,270 (95% Savings) |
| Year 3–5 Cumulative Operational Run-Rate | $2,610,000 | $128,250 | $2,481,750 |
| 5-Year Total Financial TCO | $4,152,420 | $456,000 | $3,696,420 Net Savings |
4. Production Rollout Blueprint & Long-Term Strategic Value
Enterprise deployment was rolled out via Active Directory GPO in three days. GstarLM floating license servers configured in Santiago and São Paulo allowed engineers across Chile, Peru, and Brazil to draw from a shared license pool according to project workload spikes.
Protection and control drafting teams delivered substation documentation packages two weeks ahead of schedule. The $2.28M+ preserved capital enabled the company to build a modern IEC 61850 substation digital simulator test facility.
